This invention relates to rooms for ships, constructed of metal andcapable of being taken to pieces, in which the walls, ceiling and floorconsist of standardized constructional elements 5 which can be assembledwhere required without special tools. The constructional elementsconsist of two or morespaced metal plates. The main feature resides inthe construction of the abutting edges or the connection of theindividual 10 elements together. The connection must be effected withoutthe use of additional means, such as riveting, welding and the like, andyet must be absolutely secure. It is also necessary to take care thatthere should be a possibility of 5 providing insulation between theindividual elements. Finally the possibility of a tolerance orcompensation is required in order to be able to make the rooms of anydesired shape, it being remembered that smooth walls are required. Theserequirements which are applied to the connection between theconstructional elements also apply to the connection between theelements and the ceiling and floor. It is desirable that the variousabutting edges of the elements 25 should all be of similar construction.

Metal constructional elements are known in which the abutting edges aresimilarly shaped on all sides. In some cases the abutting edges are flatand are embraced by holding means; and in other cases the constructionalelements have similarly shaped tongues and grooves, which eitherinterengage directly or are held by suitably shaped intermediate pieces.In all these cases the points of connection leave projections 35 andthus do not fulfil the requirement of providing smooth wall surfaces.Also the connecting means, for example the post-like intermediatepieces, are not suflicient for making it possible to assemble theconstructional elements in such a 40 manner as to completely close thespace. Recognizing this fact it has been proposed to provideconstructional elements with step-like abutting edges, but a connectionmade therewith does not meet the simplest requirements of a reliableassembly of the elements because a lateral bending along the abuttingedges was possible.

The invention fulfils the general requirements for constructionalelements for building up rooms for ships, which can be taken apart andin addition further considerable advantages are obtained, which in thefirst place meet the extensive endeavours at standardization in fittingout ships. At the same time there is a reduction in the original cost ofthe constructional elements 55 and in the cost of assembly.

' According to the invention use is made, for connecting theconstructional elements together, of post-like intermediate pieces,which either embrace or are embraced by the constructional plates,without forming external projections. The connection of the elementswith the ceiling and the floor is efiected by means of head and footintermediate pieces which have the same holding section as the post-likeintermediate pieces. The ceiling intermediate pieces are made in twoparts in the longitudinal direction, the two parts extending along thewall embracing the upper edge of the elements being adjustable. Further,the foot connecting piece is made roofshaped at the lower edge and issupported on wedge-shaped strips extending along the wall on both sideswhich can be drawn together by tension screws, and thus cause theelements to be clamped between the ceiling and floor. The possibility ofadjusting the ceiling and floor strip connection has the furtheradvantage that any loosening of the elements due to distortion of theship can be met by re-adjustment. It is naturally possible instead ofthe two-part ceiling and floor strips to use strips in one piece, but inorder to facilitate a completely closed assembly of the elements it ,isadvisable to have either the ceiling or the floor strip made in twoparts and adjustable.

The use according to the invention of post-like intermediate pieces andof ceiling and floor strips provided with the same holding section makesit possible to construct the elements with all the abutting edges of thesame shape, which involves considerable saving in the manufacture. It ispossible either to secure between the metal plates of the elementssimple round, oval or polygonal grooves or similarly shaped tongues atthe abutting edges by spot welding or the connecting partsmay be madedirectly from the metal plates. The abutting parts of the elements maysimultaneously serve as distance pieces for the metal plates. The desirefor standardization is met by the elements according to the invention ina manner which can scarcely be made more simple.

It is of great importance that the post-like intermediate pieces can bemade directly from insulating material so that the elements can becompletely insulated from one another. The surrounding of the post-likeintermediate pieces by the constructional elements causes a reduction ofthe static requirements thereof so that they can be made of insulatingmaterial of high quality but cheap and light.

Various constructional examples of the invention are illustrated in theaccompanying drawing. Figures 1-8 show cross-sections through theconnection points of two constructional elements,

10 connecting piece in a. round form, Figure 3 shows it in rectangularshape and Figure 4 in square shape. Figure 5 illustrates a constructionin which the abutting parts e extend outwardly like tongues, While theconnecting part (1 has correspondingly shaped groove-like engagementplaces. In Figures 6, 7, and 8 three different constructions of theconnecting parts I, g, h are shown which serve for obtaining angular orcurved walls. Naturally the connecting pieces c, d, f, g, it can behollow or solid, as required.

In Figures 9 and 10 end connections of the elements to the ceilings,floors and supports are illustrated. In the constructional form withgroovelike abutting parts b according to Figure 9, on

the one hand a rigidly connected cover strip 1' and on the otherhand around connecting piece 0 is provided. The counter member In serving forreceiving the latter is constructed in two parts with the object ofobtaining complete closure.

Figure 10 shows a form in which the two-part closure members I and m areadjustable by means of screws n, while the upper cover strip 1 directlyembraces the tongue-like abutting part e of the constructional element,the lower countermemher m has oblique surfaces 0 in roof-shapedarrangements, on which rests the connecting piece p provided withsimilar surfaces. It is therefore possible when loosening occurs toreadjust the connection, whereby the two parts of the countermember mslide like wedges below the connecting piece p and press the latterupwards.
